Jayce is one of my absolute favorite champions, and if the current top lane meta didn't favor teleport so much, I would play him a whole lot more, although I should really start playing with him in mid lane

Role in team comp

Jayce has a unique role of the "poking AD caster". He's a bruiser with a lot of poke and great all in potential. In many ways, I compare him to Nidalee. They both have amazing poke and are almost guaranteed a kill on their all ins. Both are good split pushers, though imo Nidalee has some more efficient wave clear and better escape than Jayce. But Jayce is certainly a better team fighter than Nidalee.

Often you will see Jayce in either top or mid lane, although Just Jayce has been known to play him in any and all roles

Core Items

BRUTALIZER!!! I can't stress this item enough, you absolutely need this item and really any other AD+CDR item. I personally play Jayce one of two ways: if I'm vs a top laner that I KNOW will take ignite, I'll run ignite as well and go for brut>IE>LW sorta thing.
If I'm vs a top laner that's gonna take teleport and/or just play a farm heavy lane, I take teleport as well and get tear>brut>LW and then an IE as I start getting in to mid game and ruining peoples' days.

I also really like the essence reaver item on Jayce, works especially well with his manamune

skill order
for the first 4 levels: Q>E>Q>W.
After that your priority is Q>W>E>R

power spikes

Level 2 and after he gets his brutalizer are two big ones I would say. Last whisper helps him a lot in mid game and tear can fix most of his early mana issues once he's got a few stacks so he can poke hard. But definitely level 2 and brut/tear are his notable spikes in lane

champion synergies/counters

He works really well with poke comps, as he does have enough late game damage to go the entire fight without having to switch out of cannon. He can work well with yasuo because of his knockback in hammer form. Also can work well with nami, as he can knock people into her waves+bubbles, plus her E and your W synergies very well. It slows the target and deals loads of damage.

black cleaver is the better option imo. it synergizes well with his cannon W and if you jump in with hammer Q+aa, it gets the last 2 stacks. But he definitely needs the bit of health he gets from it, though I suppose there's a 2% instance where you could build brut in to ghostblade, though it's very niche

low armor environment, you find you're having to stay in cannon form and playing as an adc WAY more than you play as an assassin/buriser deal, your enemies are mostly immobile and not building armor, so that run speed would help.

Honestly though, I think that 2% applies more to if you're either playing as a "second adc" or if you're having to cover for the adc who's like 0/28 at 10 minutes =p

Most of the time you want to evolve brut to BC though, like 98% of the time. The 2% is very rare and I would not recommend it for newer jayce players

No, because the R cooldown is flat at 6 seconds across all ranks, so you really gain nothing from leveling R. You're better off getting more early ranks in to your Q so you can hurt more and W actually. E's not worth maxing 2nd anymore because of the CD nerfs to it, so it's better to get the shorter cooldown on your tri-shot and electro field.

That used to be true but they've nerfed his E cool down hard. You used to be able to get EQ off cool down at the same time so you would max those 2 first, but now with the nerfs to the cool down you only get your E back up every 1.5-2 Qs.

W in cannon form is useful because it is an auto reset, gives 3 quick shots which are really nice when you have the armor shred debuff up. In cannon form it's a nice AoE that helps in duels/trades. Honestly the only reason you used to evolve E over W was because the cool down of E was pretty well synced with Q.

Because it's a 6 second cooldown no matter what. I get what you're getting at, but it doesn't make as much sense if you can't reduce the cooldown of the transformation, thus you can't "stance dance".

Thus, as it is right now, it's too inconsistent. You'd have to try and hold your first auto to get the armor shred and then run your damage combo, and you won't be able to always do that because of enemy outplaying, or because you don't wanna go that deep with an enemy's piling minion wave. It would be sort of the same problem Gnar suffers from, where your windows for burst+all ins are restricted to a mechanic, thus it makes you predictable. Think of it like Ziggs's passive: a good player will back off of auto range from Ziggs when he has his passive up, so that Ziggs will be forced to use the magic dmg on a minion instead of you.

Basically, though, because you can't reduce the cooldown of R, it's not practical to base your damage off of a mechanic that would otherwise make you very predictable and easy to counter. Getting max ranks in Q asap is important because of how great the base damage is and the amazing scaling on it (120%/168% of your bonus AD) and maxing your W ranks gives you free mana back in hammer and in cannon it syncs really well with when you DO get the armor shred on the enemy.

tl;dr - the armor shred buff is more of a "it's nice when you have it, but impractical to base your whole damage on it" sort of deal since you can't reduce the cooldown to stance dance.

it really comes down to personal preference and how you play Jayce. I personally like to be a lane bully and trade a lot in the early game and try to push the opponent out of farm, that's why I take arm pen marks so I can pack an extra punch with my autos (plus the armor pen from passive in cannon).

But if you find that you play for the mid/late game Jayce, where you want to farm until you get some items, you can definitely go for the butcher/feast masteries.

As far as AD reds, that's probably fine. I think armor pen reds are better for people playing aggressive early on with champions who have good base damage.

Also, on jayce, try maxing Q>E>Q for the first 3 levels, because the base damage from Q jumps really high between rank 1 and 2, so when you get 2 ranks in your Q, you'll be dealing a LOT of damage all of a sudden with your EQ cannon combo

What role does he play in a team composition?
- Jayce specializes in poke, sieging and assassinating isolated carries in the late game.

What are the core items to be built on him?
- Tear to sustain though his mana issues is highly recommended and then armor penetration and CDR (Brutalizer, Ionian Boots, Last Whisper)

What is the order of leveling up the skills?
- Max Q first, W almost always second and then E and R. Put a second point into Q at level 3 (Q, E, Q).

What are his spikes in terms of items or levels?
- Jayce spikes at level 2 (four skills), 3 (second point in his main damage ability) 9 (Q maxed), 13 (W maxed). Itemwise, he spikes with Armor Penetration, his finished Muramana and flat AD.

What champions does he synergize well with?
- Jayce synergizes very well with Champions who peel for him, protect him and poke-oriented teammates with the ability to catch people out. (Jarvan, Maokai, Braum, Karma, Lulu, Morgana, Xerath, Ziggs, Lux)

People have covered the Mid and Top lane Jayce, so I thought to create the other possible lane.

Quirky Lane: ADC

As a person who loves quirky ADCs, Jayce is interesting because he has 500 range with his range form.

What role does he play in a team composition

With ADC Jayce he isn't much different from top or mid lane. However, he is the ADC now and should be primarily used for early burst and kiting. I would think like Lucian would be a good comparison.

What are his core items

This is pretty dependent on who and how much you believe in your support. If you're duo-queuing with a strong support you can go the tear - ie - manamune route. It has extremely high burst potential and is very reliable considering his AD caster style.

If you don't believe in your support, I recommend going Triforce into BT. You'll have the survivability with stats from Triforce and almost equal burst dmg with the Tear+Ie.

What is the order of leveling up his skills

For the first couple of levels grab Q-E-W, maxing Q then W then E and R whenever you feel necessary.

The Q-E-W in the first three levels is necessary because since they'll see Jayce they might want to hard engage on you sine you're very squishy. So, if they do you should be able to burst them down pretty fast and make them disengage.

What are his spikes in terms of items or levels

Jayce, imo, doesn't really have a power spike when he plays ADC. He's pretty static throughout the laning phase. The two best power spikes for him would be when he hits level 9 (Max Q) or when Trinity/Infinity Edge is finished. Other than those, he doesn't really spike much harder. He stays relatively at the same strength all game (relative to the other ADC, as long as its not a hypercarry like Kog or Trist).

What champions does he synergize with

The best supports for Jayce would be Braum, Thresh, Nami, and Alistar. Braum + Jayce's W is pretty much an insta-stun which allows for Jayce to give off his combo pretty easily. Braum is my favorite when it comes to ADC Jayce. Thresh and Nami play the same role for ADC Jayce. They are there to protect him and create picks on the enemy ADC for him. Alistar's role with ADC Jayce is to be a Meat Wall and heavy disengage for him so he can keep landing his burst on the lane.

I wouldn't really try this in ranked because you might get shit-stomped by Tristana or Kog'Maw because of their range steroids. Along with, Jayce might be strong all the time but get behind once you will most likely never get back into the game.

I play him in both spots, but build differently early for mid, with an early hexdrinker (as most mid ad casters would). Mostly I go top, but in favorable matchups (or unfavorabel for my midlaner) I'll swap.

What role does he play in a team composition?

I play him has a bursty assasin, but if I'm behind and we need a tanky initiator, he can easily fill this role with his slow and knockback, and can easily disrupt a teamfight.

What are the core items to be built on him?

ADD: I start Mana charm 4 HP Pots and 4 Mana Pots or dorans blade.

Many people will suggest Tear as a must buy first item, followed by manamune and Infinity Edge. To me, I find that this only works if your team can survive 20 minutes without you.

In soloQ, I find this isn't the case, and lately I've opted to rush Essence Reaver, getting a BF first and a few early dorans blades for dmg and last hitting, followed by IE, then Ghost Blade and BT. With proper mana management (hard to do) you can start your power spike much earlier and actually be helpful when your teamfights break out.

What is the order of leveling up the skills?

To go with my build (without tear) I max W. Not only is W cannon form great for poking, trades, and last hitting, but W hammer form gets you mana on hit, so I'll use W cannon to poke, scare the top laner off a bit, then hammer form for mana.

If you have an unkillable top laner tank, put into his ult when you can for armor shred, but otherwise don't level R, and instead level the occasional Q. Always put one point into E for the Q E hammer form combo to disengage if you get in trouble.

What are his spikes in terms of items or levels?

When you complete BF Sword. The reason for not building manamune is that this pushes BF sword back to AFTER manamune, and it's much less of a spike until you get IE.

Definitely level 3, if to have the mana and hp to trade, you have 6 skills to get off.

I'll usually run TP, and try to force a trade at 3. Start in hammer form, wait for your R to be ready, Q onto them, W, AA, E, R, W > AA, E > Q Power slam as they run away. If you lane all that, you can win your lane in one exchange and your opponent will be scared of you.

The only problem is, this will use all your mana, hence the TP.

What champions does he synergize well with?

I have great success with Twisted Fate, with each of us ganking each others lanes. Between his Ult and stun, and your speed boosts for roaming and great ganking ability, you can easily get each others lanes fed.

I've also had great success with Braum, as Jayce's W steroid can easily pop Braum's stun.

By the time you get to fight the enemy adc, you'll have a rank 3-5 W anyway. Also, maxing W first would leave you incredibly weak in trades because the enemy can just walk out of AA range, avoid your damage and reengage when your W has run out.

That style of play, however, would basically ruin the Jayce pick as you are supposed to aggressively play the lane to punish melees in the toplane and punish squishy midlaners for their lack of resistances.

You might as well max Q first, have an easier laning phase and get to the same powerspike in the midgame. Maxing W first gives you no advantage aside from the mana regen in melee form.

And towers, and pokes. You say you are platinum, so do many plats play against Jayce by letting you land e>q skillshots often? I don't find this to be the case, as most people are smart enough to hide behind minions.

So you will spend a lot of time trying to set up EQ pokes, while missing farm. Additionally, poking with W is much less mana.

It doesn't even matter if people are good at dodging skillshots because you will still be able to hit them from the fog of war, when they are csing under a turret or point blank if they want to force a trade. If they hide behind minions and play scared, they are obviously going to miss a lot of cs, so there is no point in forcing things. This has nothing to do with division and rank or else you would basically never see skillshot champs in competitive or high elo.

I know, but what I'm saying is that the poke strategy only works with Manamune, because the mana costs are way to high on QE.

I'm not saying it's the only way to play Jayce, it's just my preferred style after the nerfs. I've played a few as poke Jayce, but it's all up to team comp. If your lanes are getting into trouble, you'll lose before you can set up, similar to a Nasus. To me, that playstyle of "I really hope this game goes 45 minutes" isn't reliable.

Yeah, I'm really sceptical on the idea of maxing W first. I'd rather Jayce be a poke machine that only goes in close when you're positive the kill can be secured. Maxing W seems like it would put him in far too much danger for how squishy he is.

Wat, those are some really strange itembuilds for jayce, the optimal items are start dorans blade, rush tear then brutaliser, bt, finish manamune, last whisper, boots of lucidity then is you need tanky go for it, and if you need more tanky you can choose between either black cleaver or another tank item, sorry if i explained badly i'm in a bit of a rush :)

That looks like season 3 Jayce, before E took a huge nerf, and his poking ability was destroyed.

I have played both kinds of builds, and I have some personal comments on those items:

Manamune Build Path

I would not like to start dorans blade on this build path (which I stopped using because poke-jayce is lackluster now and too slow of a start).

If going Tear rush, I start with the Mana charm, 4 hp pots 4 mana pots, or 3 and 3 and a ward. (Something liek that, my math and memory may be off)

Then, tear is only 500 gold so you can hit 3, do an all in trade, hopefully have 500 gold, return, grab tear and TP back.

Then, you'll want to RUSH manamune, because the stacks you get on manamune from auto attacks, this way you aren't having to spam abilities to build it up.

If you don't rush manamune, you could go tear into Brut or BF, but it feels to me too unfocused, trying to do all and doing none of it well.

Also, BT is, IMO, not better than IE. The crits from Powerslam and W steroid are just too good to prioritize lifesteal over it.

Another thing, you completely neglect Essence Reaver, which is only good for 2 champions in the game: Jayce and Yorick (and maybe Urgot).

Weather you get Manamune or not, Essence Reaver is amazing on him. With manamune, you never have to turn off the passive dmg bonus from it. Without it, it just helps you sustain prolonged sieges with your mana pool.

Basically, I was trying got play new Jayce like old jayce and it wasn't working. They severely hampered his poking, so my style of play is much less E>Q cannon spamming, which means I don't need Manamune, and can play more aggressive earlier,

I don't agree with you for the biggest part. You are basically trying to play the S2 bruiser Jayce who was never that great, was built terribly in competitive at that time (Tabi, Triforce, Cleaver rush) and only got played because his gate was broken and he demolished Darius.
His poking ability is not even remotely destroyed. They just removed the toxic part of his kit (spamming the acceleration gate every 6 seconds with 40% CDR) and delayed his powerspike with the tear nerfs (which has nothing to do with his poking ability). You will still get to use the gate every 10-11 seconds in the lategame and you'll still get your Muramana after 20-25 minutes.

Also, the faerie charm start is not recommended anymore. Nowadays it's either DBlade or Longsword in 95% of the cases. The only viable option is to start Flask in a really tough matchup in the midlane. It really does not matter if you pay 520 or 700g for the tear, it does however make a difference if you start the game with no combat stats.
The Manamune rush is also not that great anymore since Brutalizer and Last Whisper will give you a bigger damage spike and you will stack the Tear about as fast as with Manamune with the new passive stacking they added a few patches ago. Just spam your W (does not matter if melee or ranged) as often as possible and you will end up with the completed Muramana at about 25 minutes.

I agree with IE > BT. Essence Reaver might be ok, but the mana regen is nearly useless in the lategame and there are more efficient and cheaper items for the early and midgame, I would only get it for the CDR. I'd recommend you to watch JustJayce on twitch. Watching him made me understand all powerspikes and the importancy of certain items on him and my winrate with Jayce skyrocketed to 72%.

tl;dr
DBlade, Tear, Brutalizer, CDR Boots, LW, finish Muramana, IE, finish Ghostblade, BT (or Essence Reaver if you really prefer it). Bruiser Jayce is vastly inferior to a glasscannon build because he will do less damage and he should never soak up any damage.

You AA AND spam spells on your opponents and the Muramana is useful to sustain through the spell usage and amplifying your (Hyper Charge) AA damage. If you don't want the Muramana because you prefer an earlier power spike, then it's perfectly fine. But your reasoning is strange - if you AA a lot, the Muramana is great. If you think it is unnecessary because you don't find yourself using spells, then you are not playing to the full capabilities of Jayce.

Ahh, one of my old favourites, Jayce mid, who was my goto champ before I started maining jungle and support.

-What role does he play in a team composition?

Poke. Siege. Poke. Siege. Jayce is one of the best pokers in the game, with his EQ combo being able to chunk down carries. He can either get the carries from the other team low enough for his team to engage, or force them back and get an objective. He shines in poke and siege team compositions, as he is excellent at disengaging with both cannon and hammer E, and can go in with melee form if needed.

-What are the core items to be built on him?

Focus on a mix of AD and cooldown reduction, and build a muramana to settle Jayce's mana problems (with blue buff if possible, which i usually get cause I play mid Jayce). AD and CDR allows him to spam his EQ (or just Q) combo frequently, and the more poke you are able to dish out, the better Jayce will be in teamfights or sieges.

I personally start with Long Sword, 2 health and 1 mana potion, allowing him to dish out damage in the laning phase, while having the sustain to not be forced out of lane easily. After that, my full build would be Tear-Tier 1 Boots-Brutalizer-CDR boots-Manamune-Last Whisper-Infinity Edge(cause lifesteal isnt important on him, and W with crits from IE is INSANE), Guardian Angel, and lastly upgrade Brutalizer to Black Cleaver.
You can consider getting Trinity Force instead of Infinity Edge if you want, but buy it before you get Manamune, as it's only really strong once you completed the full item. Also consider getting an early hexdrinker (before Manamune again) instead of Infinity edged if you are getting owned by an enemy AP midlaner, its not worth dying constantly and to fall behind even more (thx louiscool for your post that reminded me)

-What is the order of leveling up the skills?

There are 2 ways you can go for from lvl 1-3, and two ways of maxing skills up to lvl 18.

Lvl 1-3 option 1: W-Q-E, my personal favourite. Why W? At level 1, most enemy midlaners will expect you to take Q. As most of them are ranged casters, they will not have as much armor as other champions, and with a single AA(Cannon bonus)-Wx3, you will take them to half health at level 1, which is a HUGE advantage for you. Then I take Q at level 2 to poke with, and possibly go melee Q to gapclose for a kill, and E at level 3 for the EQ combo as well as the percent health damage on melee E.

Option 2: Q-E-Q- This is the more popular start, as you unlock a strong EQ combo at level 2, and you can easily all in by then. You can constantly poke with Q at level 1, and by getting 2 points in Q at level 3, you are going to poke harder than the above skill set.

Normal Maxing to Lvl 18:

Option 1: Q>W>E>R I see most players doing this now. The cooldown of acceleration gate does not go down with level, so you max it third, and though the execute percent health damage increases, three procs of W at max rank is "safer" and can deal just as much damage. Obviously max Q first for the poke, and get R at lvls 16, 17 and 18 cause its not worth getting points in it for meagre stats.

Option 2: Q>E>W>R Oldschool method,where usually you dont take W until level 11 with this build. This build focuses a lot on poking with EQ, then following up with melee EQ to deal tons of damage quickly. Other than that its about the same as above.

-What are his spikes in terms of items or levels?

If you use level 1-3 skill order-Level 1 is already your spike. You can deal massive damage with a simple combo, forcing the enemy to play more passively as another combo could force him out of lane, which helps a TON.

Level 2(build 2) and Level 3(build 1) is another spike. At these levels, you have access to the QE combo, allowing you to chunk opponents for good damage, and makes it extremely for you to all in them and get a kill/summoner spells. At worse you force them out of lane and you get a CS and experience advantage.

What champions does he synergize well with?

-Generally, he synergizes with other champions with good poke, and champions with good sustain and/or disengage. I always like Janna support with Jayce, as her shield will give you bonus AD to make your combos hurt even more, and she is excellent at disengaging if you havent chunked the enemy carries down to a point where your team can burst them down.

I wouldn't say that he HAS to have excellent synergy with each champion, as he is already strong in YOLOQ on his own.

My take on Jayce: The cooldown on his E is ridiculously high in my opinion, at 0% CDR you literally have to wait 16 seconds just to pull of a EQ combo, which is excruciatingly slow considering how other champions can deal even more poke damage during that duration (I'm looking at you Xerath). He has a dominant laning phase that he has to take advantage of, and falling behind can be crippling since Jayce isn't exactly the best teamfighter. However, I still think that he is an amazing champion in the midlane due to the number of squishy champions there, and he has seen a rise in popularity recently because he is able to punish most assassins with their weak laning phase.

I've tried out Jayce's "alternative look" build in Dominion and had a lot of fun with it. Haven't had played it on SR because all of the server DDOS stuff lately has made it impossible to play. I suspect it'll do very well, though, especially with a Flask start. Not sure if it brings enough damage to kill one of the meta toplaners like Maokai, but you should have what you need to at least break even and be effective in teamfights.

Beginning to think that Manamune on him is a trap, which partially explains why he's fallen out of favour these days. Yes, you can get the triple-proc, but you're almost guaranteed to lose lane to get it.

It works rather well, actually. You just need to be patient. Your first clear is pretty slow, (Blue-wolves-Wraiths-Red), but after you get elder lizard you're golden. Level Maxes go as follows: W-Q-E-R.

Item build- Lizard-Boots (CDR or Mobility) - Essence Reaver (once you get this, you can give your mid laner blue, until then, you're going to need almost every one.) - IE - LW - GA. This item build leaves you a little on the squishy side, so only do it if you are confident in your team being able to well, and I would usually only do this if you have a beefy top laner. If you do not, I would sub in a tankier item based on their team comp for the GA.

Best way for you to gank a lane is to roll in as your cannon form, drop your gate, and Q through it to land a decent amount of damage. After doing so, click W, shift into hammer form and Q onto the enemy. This will USUALLY draw their flash, but if it is down, run ahead of the enemy and E them back into your teammate who should be able to secure the kill.

You should be a very active jungler in order to help fund your expensive item build, plus, your early game damage is pretty massive which is good for securing those early kills.

I saw it in ranked once, it did destroy us but if that is because of the pick or not im unsure. I have never tried it myself but it probably works decently, i really dont see many issues with it in theory. I guess his clear would be decent with so many AOE+single target spells. Maybe he would have mana issues without Tear. Jayce's scaling would be pretty decent. his cc is poop but you make up for that with good mobility and burst dmg for ganks.

I find its good for the cdr and dmg but im still unsure if its that good. I tried max cdr buils and you can spam skills a lot, but i also tried the IE build and the 1-1.4k crits are pretty op when you have max attack speed.

its not a bad item. Its about how the game is going etc. If i get super fed in lane. im going IE and im gona crit 600 at 20 minutes into the game. If i get wrecked im gona go for the safer build with a quicker power curve.

YES, my time to shine! It's my first time doing one of these but if you want more info just ask away and i can go pretty in depth.

Role: depends on situation/build/playstyle. Can be played as Assassin(in teamfighting)/Poke/Splitpusher/Peeler(in teamfighting)/Adc(in teamfighting).

Core items: Dorans+pot>Tear of the goddess>Boots(upgrade to boots of lucidity or merc treads later on)>Brutalizer>Muramana/IE/BT/LW. Other situational items are advised.

Skills: Q W E R In that order.

Spikes: Lvl 4-5 when your Q starts doing REAL damage. Lvl 7 when you get lvl 3 in your W. Lvl 9 when you get lvl 5 in your W. Spike when you buy Brutalizer. Spike when you buy BF sword, or complete IE/BT/LW. Spike when you complete manamune stacks.

Synergize well with: I'm not sure, he is a very soloq champion and has his part to play in the team, but i'm not sure if his kit really allows him to synergize amazingly with anyone in particular, except for maybe karma or orianna.

He synergizes pretty strongly with ziggs. Ziggs can both provide poke if going for siege, provide waveclear if going for splt(or just split himself lol), provide strong peel if going for a protect the vayne comp, provide decent sustained (magical) damage, or provide extra burst if going for an assassin.

One minute, I need to think of why ziggs isn't the AP version of cannon-form jayce (the one I usually stick to after laning phase).

Jayce master race, lots of ways to build him, and I build differently than most.

What role does he play in a team composition?

His role is to be at the top of the "damage dealt to champions" chart. Simple as that. He can be poke, assassin, or duelist, just dish out damage in whichever way is your job.

What are the core items to be built on him?

The items I personally go are flask 3 pots > tear > er > lucidity > LW/BC > LW/BC > BT. Really any significant ad item works, I just like my build since it also has max cdr, 30% lifesteal and mad muramana damage. I go ER and muramana since muramana scales off %current mana, so a jayce w at 2000 mana deals a few hundred more than a jayce w at 500 mana.

What is the order of leveling up the skills?

I max q>w>r>e. You get r to start, so while maxing q at 9, you also have 3 ranks in w at 9 as well, maxing out at 11 instead of the standard 13. You spike faster, it's pretty simple. It does depend on style though, if you go between melee and ranged a lot then obviously r is better.

What are his spikes in terms of items or levels?

Spikes are at ER completion, muramana transform, LW/BC finish. Obviously he doesn't spike with tear or boots, only with the big items. For levels lv 3/4, lv 9, lv 11 (depending on level order), not that much later levels.

What champions does he synergize well with?

A heavy disengage/counterengage support like nami/braum, jungler with hard cc for ganks.

I like to play him at mid and top. I tried him also on the other positions but I dont think he is good at them. Jungle is horrible without early kills, also heavy mana problems without blue and cooldown issues. As an ADC his abilities are hard to land and range is too short. For support he has also too much mana problems, poor CC and lacks good base damage.

Mercurial against suppression and heavy CC in general.
BT if I really need sustain.

I always try to rush brutalizer, because it gives great laning strength, but my muramana will delay a bit.

In teamfights he peels for his carries and hides behind a good frontline or tries to disengage and burst the tank down with his team. He is great at sieges because of his poke and his hyper charge can take turrets pretty quick.

His power spike are at level 4 and 5. At 6 he falls off due to no real ultimate. He is also pretty strong if you have bruta and LW or IE and youmuus.

I max Q first because I think W scales only good with items. His base ad is quite low and due to the short range its quite easy to get minion aggro. W second, E third and ultimate last.

He fits actually in many team comps, my most favorite are teams with heavy poke and/or a lot of disengage (Xerath, Ziggs, Janna, Elise, Zilean, Lulu, Khazix). He is also a quite safe pick at least at mid lane. I think only Fiora could be problematic, but she is rarely picked.

Jayce mains, how do you deal with Mordekaiser? I had a Jayce top lane in my last game, and Mordekaiser went up against him. Though we managed to win through teamfights, Mordekaiser completely wrecked Jayce. I'd like to know what Jayce could have done to mitigate Morde getting fed, as even farming under turret didn't help him much, and Morde warded very well, preventing quite a few of my ganks on top lane.

I really like Jayce, I started it since Nyjacky used to play him when he was on Curse, by that time I couldn't play it because I was bad and did not undersand neither his skills nor most of the game's.

Recently, I found this group of guys that stream in only one channel at twitch called "Ganked by Korean TV", as the name says they are all korean even though some play in different servers. They are those kind of players which mains an champion or two and only play it, if you want and can learn just by watching someone play, that's your to go. There are Ahri, Viktor, Heimedinger, Urgot, AP Kog'maw, Kha'zix mains, and the thing that matters for this topic: two really great Jayce players, from who I learned to play this champion.

PS:I didn't come here to share ths stream so I just told a little about it, if you want info, look for it or message me, I'm just a fan that enjoys the channel.

I like to build manamune, essence reaver, iceborn/black cleaver, last whisper, BOTRK, and guardian angel. With this, your E + Q combo POPS even the tanks, and when you go in on a teamfight it's basically gg for the other team.
